The Zagreb indices of Some of Nanotube

A graph is a mathematical model that is used to predict the topology of a previously determined system. In chemical graph theory, a graph is designed by considering atoms as edges and vertices as links between specific molecular atoms. A topological index is a numeric quantity from the structure of a graph which is invariant under automorphisms of the graph under consideration. Also the edge version of Zagreb index of graphs is introduced based on the end-vertex degrees of edges of their line graphs. In this paper, we computed the Zagreb and edge Zagreb indices for HAC ۵C۷ [p,q] and HAC ۵C۶C۷[p,q] nanotubes.
